MMX BMW G8X Differential Heat Shields For G80/G81 M3, G82/G83 M4 & G87 M2 (Pair)The MMX Differential Heat Shields are designed to protect the rear differential of the BMW G8X M3, M4, and M2 from excessive heat exposure, ensuring consistent performance and long term reliability. High temperatures from the exhaust system can cause differential fluid to degrade, leading to increased wear and reduced efficiency. These heat shields act as a thermal barrier, minimising heat transfer and helping to maintain optimal operating conditions.
